Power Quality and Energy Efficiency Why do we need reactive power compensation and harmonic filtering? Reactive Power Compensation Connected equipment (transformers, motors, air-conditioning, refrigerators, etc.) cause a phase angle between current and voltage. When the current is phase-shifted, it takes more current to deliver the same amount of active power. (deteriorated active power) Active Power Active Power Dephasing between current Power factor = and voltage decreases the Active power / active power (only the Apparent power active power is converted into useful mechanical power)

Power Quality and Energy Efficiency High Voltage Special Capacitor Units High Voltage Surge Protection Capacitor Units Medium voltage rotating machines and transformers can be exposed to abnormal voltages (transient overvoltages or surges) due to internal or external reasons. The causes are: Capacitor bank switching on the connected power systems Operation of vacuum circuit breakers System faults Lightning These surges can cause damage to the turn-to-turn insulation of rotating machines and transformers. Connecting surge capacitor units from line to ground prevents this damage by bringing...

Power Quality and Energy Efficiency HV Iron-Core Reactors The filter reactors are connected in series with the capacitor units to form a series resonant circuit with a very low impedance. Advantages Reactive power compensation (power factor correction) in networks with harmonics Reduction of inrush currents that flow from step to step of the capacitor banks when switched Avoiding the risk of resonance as the LC circuit is having a resonance frequency below the first existing harmonic Decrease the level of harmonic distortion as the circuit is also having a certain tuning frequency at which...
